Step-by-Step Usage Guide for XIZI Otis CLT-05024A Switching Power Supply

To ensure the stable operation of the XIZI Otis elevator system and extend the service life of the CLT-05024A switching power supply, follow the professional guidelines provided by Nanjing Zhuye Elevatorparts for installation, operation, and maintenance:

1. Professional Installation & Commissioning

Installation must be performed by certified technicians familiar with XIZI Otis elevator systems. Prior to installation, confirm the compatibility of the CLT-05024A with the target XIZI Otis elevator model using the detailed compatibility manual provided by Nanjing Zhuye Elevatorparts. The steps are as follows:

Safety Preparation: Cut off the elevator’s main power supply and the power supply of the control cabinet, and hang a “Maintenance in Progress—Do Not Power On” sign at the power switch. Open the elevator control cabinet and locate the original power supply installation position. Clean the installation area to remove dust, oil stains, and debris that may affect heat dissipation or electrical contact.
Power Supply Installation: Align the CLT-05024A switching power supply with the mounting holes in the control cabinet and fix it firmly using high-strength screws provided by Nanjing Zhuye Elevatorparts. Ensure the power supply is installed vertically to facilitate heat dissipation (the heat dissipation holes on the shell must not be blocked). Reserve a 5–10cm gap around the power supply to avoid heat accumulation.
Wiring & Connection: Follow XIZI Otis’ official wiring diagram and Nanjing Zhuye’s technical guidance to connect the power supply. Connect the AC input terminal (L, N, PE) to the corresponding power source in the control cabinet, and the DC output terminal (24V+, 24V-) to the elevator control system and other load components. Ensure the wiring is tight, the positive and negative poles are correctly connected (reverse connection will damage the power supply and load), and use insulating tape to wrap the connection points. Connect the ground wire reliably to enhance safety and anti-interference performance.
Post-Installation Testing: Restore the power supply and conduct comprehensive functional tests. Use a multimeter to detect the DC output voltage of the CLT-05024A (standard value: 24V ± 0.5V). Operate the elevator to run in normal mode and inspection mode, and check if the control system, door operator, emergency lighting, and other components operate normally. Simulate load changes (e.g., turning on/off the elevator fan) to verify the power supply’s voltage stability. If the output voltage is abnormal or the elevator components malfunction, recheck the wiring and installation immediately.

2. Daily Operation & Routine Inspection

Regular inspections are crucial to early detection of power supply faults and ensuring the reliable operation of the elevator system. Maintenance personnel should incorporate the following checks into their daily patrols:

Daily Visual Inspection: During control cabinet inspection, check the external state of the CLT-05024A. Ensure the metal shell is free of deformation, corrosion, or damage; check the power indicator light (normal operation: green light on); confirm that the wiring terminals are tight, no loose wires, and the insulation layer is intact.
Weekly Functional Check: Use a multimeter to detect the DC output voltage of the power supply (record the data for comparison). Check if the elevator control system displays any power-related faults (e.g., low voltage alarm). If the output voltage fluctuates excessively or there is an abnormal alarm, inspect the power supply and load components immediately.
Monthly Parameter Monitoring: Cut off the power supply, remove the wiring, and use a megohmmeter to detect the insulation resistance between the input terminal and the ground, and between the output terminal and the ground (normal value ≥ 100MΩ). Check the heat dissipation of the power supply—if the shell is abnormally hot during operation, it may indicate a fault such as overload or internal component damage.

3. Regular Maintenance Schedule

Systematic maintenance can effectively extend the service life of the CLT-05024A switching power supply. Follow Nanjing Zhuye Elevatorparts’ recommended maintenance plan:

Quarterly Maintenance: Clean the surface of the power supply and the surrounding area of the control cabinet with a dry, lint-free cloth to remove accumulated dust (dust accumulation will affect heat dissipation). Recheck the tightness of the wiring terminals and retighten any loose terminals. Inspect the power supply’s cooling fan (if equipped) for flexible rotation—replace the fan if it is stuck or makes abnormal noise.
Semi-Annual Performance Test: Conduct a comprehensive performance test, including conversion efficiency, voltage stability, and protection function verification. Use a professional power supply tester to simulate overvoltage, overcurrent, and short-circuit conditions and confirm that the protection circuit is triggered normally. For elevators in harsh environments (such as high humidity, high temperature, or strong electromagnetic interference), increase the frequency of performance tests.
Annual Professional Overhaul: Arrange a professional inspection with Nanjing Zhuye Elevatorparts’ certified technical team. Disassemble the power supply (by professional personnel) to inspect internal components (including capacitors, resistors, and transformers) for aging or damage, and replace them with genuine XIZI Otis components. Conduct a full-range performance calibration to ensure the power supply meets the original factory standards.

Recommended Replacement Cycle for XIZI Otis CLT-05024A Switching Power Supply

As a core electrical component bearing long-term load operation and electrical aging, the CLT-05024A switching power supply has a specified service life. Timely replacement is critical to avoiding power supply failure, which may lead to elevator control system shutdown, door operation failure, or even emergency system malfunction, affecting elevator safety.

1. Standard Replacement Cycle

Under normal operating conditions (elevator daily operation time 12–24 hours, control cabinet environment temperature 0–40℃, humidity 10%–85%, no severe dust or electromagnetic interference), the recommended replacement cycle for the XIZI Otis CLT-05024A switching power supply is5–7 years. This cycle is determined based on Nanjing Zhuye Elevatorparts’ long-term field data, including component aging tests, performance degradation analysis, and XIZI Otis’ original component service life standards.

2. Adjustments for Special Scenarios

Harsh Environments: For elevators in high-humidity coastal areas, high-dust construction sites, control cabinets with poor ventilation (resulting in high temperature), or areas near industrial equipment with strong electromagnetic interference, the replacement cycle should be shortened to3–5 years. Harsh conditions accelerate the aging of internal components, reduce insulation performance, and increase the risk of power supply failure.
Low-Frequency Use Scenarios: For elevators with low usage frequency (e.g., villa elevators, small office buildings with monthly rides < 2,500) and well-ventilated, clean control cabinet environments, the replacement cycle can be appropriately extended to 7–8 years—only if Nanjing Zhuye’s professional inspection confirms that the power supply’s output stability, conversion efficiency, and protection functions are all intact.

3. Immediate Replacement Conditions

Replace the CLT-05024A switching power supply immediately if any of the following issues occur, regardless of service life:

The DC output voltage fluctuates excessively (exceeding 24V ± 1V) and cannot be restored to normal through adjustment or maintenance.
The power supply frequently triggers protection functions (overvoltage, overcurrent, short-circuit) without obvious load faults, indicating internal component damage.
The power supply shell is abnormally hot during operation, or there is a burning smell, sparking, or abnormal noise (such as buzzing), posing fire risks.
After professional testing, the conversion efficiency is lower than 75%, or the insulation resistance is persistently lower than 10MΩ, indicating serious performance degradation.
